JOHN F. SIPE AND HARRY E. SIPE, OF NEW YORK, N. Y. SPRING-WHEEL .EOR VEHICLES.

Specification of Letters Patent. Patented D00. 2,1913. Application filed December 24, 1909. Serial No. 534,820.

To all whom it may concern.

Be it known that we, JoI-IN F. SIDE and HARRY E. SIDE, citizens of the United States, and residents of New York city, in the county and State of New York, have invented certain new and useful Improvements in Spring-lVheels for Vehicles, of which the following is a specification.

)ur invention relates to improvements in spring wheels and the object of the invention is to supply a resilient wheel, very simple in construction, compact in design and of great lateral and vertical strength.

Another object of the invention is to secure great resilience without any of the disadvantages residing in spring wheels which are constructed with joints or connections having parts that move one upon another.

n the present invention ample movement is secured between the hub member and the tread member and entirely by reason of the movement of the springs themselves, thus avoiding the noise, the wear and tear and also the multiplicity of parts present in spring wheels which have connections or joints with movable parts between the springs and the members or where there is sliding contact to furnish lateral strength.

Another object of the invention is to eliminate all the parts ordinarily employed between the hub member and .the tread member, except the springs themselves, thus doing away with the brackets, plates and movable joints ordinarily employed.

Another object of our invention is to ply a spring wheel of great durability.

he invention is illustrated in the accompanying drawings in which Figure 1 is a side View of a embodying the said invention; and Fig. 2 such a pair of springs are bolted to the folly is a crosssection of of the hub member and to each other by part of the hub member on the line 2-2 of means of the bolts 11, as Shown in Fig. 2.

5 is a wooden felly constituting a part of the tread member of the wheel. This wooden folly is preferably made three inches larger in inside diameter than the outside diameter of the steel band 4 of the hub member.

(3 is a steel band which is fastened in any suitable manner to the periphery of the fell 5.

7 is a thin solid rubber tened in any suitable surface of the band (3.

8, 8 are side plates which are preferably annular in form and which are bolted or otherwise suitably fastened to the sides of the felly The parts from 5 to 8 inclusive constitute a wheel member containing a tread, or what may be called the tread member. The tread member is made about two inches wider than the folly of the hub mem- 9, 9 are specially wound flat coiled springs by means of which the hub member and the tread member are connected together in such a manner as to suspend the hub member within the tread member on the springs.

hese springs are wound open, one coil within another. They are arranged in two series on opposite sides of the plane of the wheel, that is to say, one series is on one side of the plane of the wheel and the other series is on the other side of the plane of the wheel.

In the best form of the invention, namely that illustrated in the drawings, the inner end of the spring is bent inwardly and bolted or otherwise fastened to the side of the felly of the hub member as represented at 10. The springs are preferably arranged in pairs, as shown, and the inner ends of tire which is fasmanner to the outer sup- Flg. 1, showing the manner in which the The outer ends of the springs are bent outsprings are connected with the said memwardly so as to extend down the side of the annular plate 8 as shown at 12 in Fig. 2.

13, 13 are clamping plates adapted to fit over the outer ends of the springs and the parts are by the bolts 15 5. and of the springs with the tread member, as clearly shown in It will be seen that the outer end of each spring is connected with the side of the tread member or near the side thereof so that a sutlicient space is left between the springs on one side of the Wheel and the ers.

Similar numbers indicate similar parts in the two figures.

Referring to the drawings, 1 is the hub of a wheel, 2, 2 are the spokes.

3 is a wooden felly, 4 is a steel band attached in any suitable manner to the periphery of the telly 3.

he parts already enumerated constitute the wheel member containing the hub, or what may be called the hub member of the wheel.

springs on the other side ot the wheel to the springs operate together at all times allow the hub member to be suspen ed be in opposmg the load carried by the hub tween the two series ot sprin s and to have member. a certain sidewise play between the two be- "What we claim as new and desire to secure by Letters Patent, 1s:

1. In a spring wheel the combination ot a wheel member containing a hub, the telly 3, connecting parts between the hub and the tore it will strike against the edges ot the coils of the springs. It will be seen that the two members ot the wheel are spaced circumterentially apart and that one series of the springs lie on one side ot the hub memtelly, the telly 5 made wider than the telly her and the other series of springs lie on 8 and provided with a suitable tire, an the the other side of the hub member, thus alseparate and independently operating lowing the hub member to move vertically strong fiat coiled springs 9 having their inor eccentrically between the two series 0 ner ends bent inwardly and secured to the side ot the telly 3, and having their outer ends secured to the telly 5 near t e edges thereof so as to rest upon the inner tace ot the telly, whereby the hub member is sussprings. It will also ot the springs are set edgewise ot the hub thus afiord a strong lateral side of the We prefer to make the springs of strap pended between the springs and the outer steel about three'tourths ot an inch wide coils ot the springs torm stops to limit the and one-eighth ot an inch thick. We usulateral motion ot the hub member and the springs are supported by the inner tace o the telly, substantially as shown and escribed.

2. In a spring wheel the combination ot a wheel member containing a hub, a telly 3, connecting parts between the hub and the telly, the telly 5 made wider than the telly 3 and provided with a suitable tire, the strong fiat coiled springs 9 having several coils one within another, and having their inner ends bent inwardly and secured to the side of the telly 3 and having their outer ends bent outwardly so as to fit against the sides and inner tace ot the telly 5, and .clamping plates 13 to clamp the outer ends of the springs to the telly 5, substantially as shown and described.

In testimony whereot, we

ally employ twelve pairs ot these springs to each wheel, twelve springs on each side ot the wheel. This construction allows tor the vertical and eccentric movement ot the hub member in relation to the tread member tor a distance 0t one and one halt inches in all directions, since the space between the hub member and the tread member is entirely unoccupied. The springs themselves create a yielding lateral stop tor the hub member in relation to the tread member since the inner coils will allow a slight lateral movement betore the hub member comes in contact with the outer coils ot the springs. The springs themselves operate as a yielding torsional stop.

Our improvement secures a great deal of resiliency and strength. The construction have signed our is simple, compact and economical. ll of names to this specification, in the presence the springs in this construction are placed of two subscribing witnesses.
